stare at then look on a plain wall as see christ, turin shroud? style.

adifferent angle.

going in same up direction (all joined), mentally exhausting it was.

This one always amazes me, square A and B are the same colour
The image above shows what appears to be a black and white checker-board with a green cylinder resting on it that casts a shadow diagonally across the middle of the board. The black and white squares are actually different shades of gray. The image has been constructed so that "white" squares in the shadow, one of which is labeled "B," are actually the exact same gray value as "black" squares outside the shadow, one of which is labeled "A." The two squares A and B appear very different as a result of the illusion. A second version of the same picture includes a rectangular bridge connecting square A and B to show they are the same shade of gray.
